. To all whom it may concern:

Be it known that I, GUSTAVE E. W. MIL- Len, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts, have invented a new and useful Device for Mountlng Mirrors on Telephone Transmitters, of which the following is a specification' This invention relates to a mounting for a mirror suitable forapplication to the ex terior surface of a telephone transmitter head.

The principal object of the invention is to provide a-convenient and simple'means for mounting a mirror on a telephone transmitter without interfering with the mouth piece in anyway or running any risk of preferably of metal but not having it firmly and securely put back in position. The invention also "involves means whereby the attaching member which connects the mirror with the telephone head is located in proper position and prevented from moving circumferentially or axially on the head. The invention also involves details of construction as will appear. Reference is to be had 'tothe accompanying drawings in which-- Fig. 1 is a front elevation of a part of a telephone transmitter with a preferred embodiment of this invention applied thereto;

Fig. 2 is a side View, and i Fig. 3 is a perspective view of the attaching band and connected parts.

The invention is designed particularly to provide a mirror in a convenient place for any person using a telephone with the end in view of providing for automatically and unconsciously correcting any defect in the facial expression of the operator and thus also unconsciously favorably affecting the impression which she gives over the line as well as having the same effect more permanently on the individual.

In the form of the invention shown, the ordinary telephone transmitter head 10 is illustrated. The mouth piece 11 is not disturbed, removed or replaced in the application of the mirror thereto, in accordance with this invention.

The mirror itself comprises a back 20, capable ofbeing made of hard rubber, composition, celluloid, wood or the like. This back is provided with a flange 21 around its edge of any desired shape to provide for the desired form is located just inside. the

together as far as possible so that grip the same. Then the screw is inserted it to avoid of mirror. all the way around except at the bottom. -Within it there isa bead ring 22 of metal which is continuous all the way around and flange. This holds the beveled edge of the glass 28, which in the form shown is elliptical, but may be of any desired form. j 1 1 The bottom of the back is bent inwardlya short distance at the bottom of the mirror to provide a flat projection 24 paral- This flange is bent over inwardly lel with the back and-with the face of the glass. Thus the mirror frame and itssupporting element can be stamped from a single piece of sheet metah lVith the glass these parts constitute a unit. This projection extends from the front edge of a transversesection 25, partaking ofthe shape of the bottom of the glass, and is integral with the back extension 26 on thebottom of the bead ring which occupies the space across the projection at the top of it from the end of the flange on one side to the end of it on the other. The head ring serves to hold the glass in position, and this extension on it serves to complete the flange 21 at the bot tom. Its ends are welded or otherwise secured to the ends of the flange and the joints are finished over so that they'do not show in the completed article, although they are indicated at 28 on the drawings. This projection is riveted to a projection 30extending downwardly in a plane from the top of an expanding circular band of sheet metal 31 or other convenient material. This band is intended to surround the transmitter head and is provided with a pair of lips 32 extending from the opposite ends of the. band and arranged parallelwith each other. These project downwardly at the bottom in a convenient position. They are both perforated and these perforations are threaded. Through these threaded perfora tions passes a screw 34 having a slotted head so that it can be inserted by means of a screw driver.

It will be understood, that in the tion of the band, it is placed around a telephone head 10 and the two lips pressed it will and turned. A check nut is placed on accidental unscrewing, but the screw holds the parts in position by its con applicathe fact that modifications can be made nection with the two screw threaded perforatlons. Any desired connection can be employed for this purpose.

As stated, the top of this band is provided with an extensionpiece 3O bent over 1n front downwardly with a grooved arouate portion at the top. This fits the raised head. -These actto lock the mirror in up right central position, although they may be employed tolock it at right angles thereto, in the present case, as there are four of them equally spaced apart.

This band with its extension piece is formed from a single piece of metal, preferably, or other suitable material for the purpose. It is inexpensive to manufacture, and forms an effective support for. the mirror, although it may be formed of Nery thin metal. a

Although I have illustrated and described only a single form of the invention, and illustrated only one design, I am aware of therein by any person slzilled in the art without departing from the scope of the inventionas expressed in the claims. Therefore, I do not wish to be limited to all the details of construction herein shown and described, but what I do claim is 1. Theattachment for a telephone transmitter head, comprising an eXpansible circular band surrounding it and detachably secured thereto and having a projection provided with a groove behind it to fit over the usual raised ridge on the transmitter head, a mirror back mounted on the project-ion, and a glass mounted on the front of said back. v

2. As an article of manufacture, an attaclnnent for a telephone transmitter comprising a split band of vmetalqadapted to surround the transmitter head and having means at the bottom for clamping itthere:
